Biography
O'Horan was the son of Tomas Antonio O'Horan y Arguello and Maria Gertrudis Escudero de la Rocha. His paternal grandfather John O'Horan came from Aughane, Ireland to Yucatan by way of the Canary Islands while his mother was from Campeche. The elder Tomas O'Horan served in the Mexican senate representing Yucatan in 1835, having been a Mexican politician previously. Tomas O'Horan Escudero was of Irish and Mexican descent.

Originally serving in the Texan Revolution, Pastry War, and Mexican-American War, O'Horan became a general of Benito Juarez's Liberals who fought in a civil war from 1859 to 1862, and then fought the French. At the Battle of Atlixco on May 4, 1862 O'Horan defeated Leonardo Marquez's French army marching on Puebla. During the Battle of Puebla he attempted to lead a supply convoy to asist the city but failed, and he later defected to the French, who appointed him Prefect of the Valley of Mexico under Emperor Maximiliano I of Mexico.

When Benito Juarez, aided by the American Legion of Honor, recaptured Mexico City, O'Horan was implicated in the betrayal of the Mexican people and was executed by firing squad.
